SPECIFICATION forming part of Letters Patent No. 583,724, dated June 1,1897. Application filed January 23, 1897. Serial No. 620,492- (Nomodel.)

To aZZ whom it may concern:

Be it known that we, ADOLPH BEROKHE- MER, of the city of Brooklyn,county of Kings, and GEORGE W. SPITZER, of the city and county of NewYork, State of New York, have invented a certain new and usefulImprovement in Windows; and we do herebydeclare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, making a part of the same, in which Figure 1represents a front View. Fig. 2 represents afront View of the lower sashwith part of the window-facing removed, and Fig.

I 5 3 is a horizontal section of the window-frame with both sasheslowered. Fig. at represents a view of the window-frame with latch-pinsopen and closed. Fig. 5 represents a top View of the sash withslide-staples attached.

Fig. 6 represents a bottom view of the sash with latch-pins andslide-staples attached and in position.

Our invention consists in, certain improvements in windows whereby thesash can be swung open inwardly, as well as raised and loweredvertically, so that the outside of the sash or glass attached theretocan be cleaned and repaired without the necessity of going on theoutside of the window-frame to do so,

0 thereby obviating the danger (if the window is any height from theground) attendant thereto.

The manner of constructing and operating the said improvements is asfollows: Wife 5 take an ordinary window-frame (see Fig. 1, A) havingattached thereto one or more sash B,sliding up and down betweenparting-s trips or stop-beads O, D, H, and J, preferably two sash, andon the inner side of the Window- 0 frame, preferably on parting-strips Gand H, or in any convenient position thereon, are formed or otherwiseplaced latch-pins E, so formed that they can be folded up (see Fig. 4, Ewhen not in use, and on the top and bottom of the sash (or nearly so)place or otherwise form slide-staples, (see Figs. 1, 3, 5, and 6, L,) sothat when the sash is brought down ,per sash requires to be swung theslide-staplesLwill fit over the pin-latches E, thereby forming a pivotor hinge to the sash, so that it can swing open inwardly. (See Fig. 1.)As this cannot be accomplished without the stop-bead J being removed, wecut the stop-bead J at or about the height of the lower sash, and thelower portion thereof we hang with common hinges, so that it can beswung outwardly from the window-frame A, thereby allowing the lower sashto be swung inwardly at pleasure. Then the upinwardly for the purpose ofthe cleansing or repair of its outer surface, it is brought down so thatthe latch-pin E and slide-staples L can be suitably adjusted or pivoted,when the upper sash will swing open inwardly, if released by theparting-strip or stop-bead C. To accomplish this, we cut the stopbead Cat about the height of the lower sash and so form the said stop-bead Othat it can be pressed back into a socket formed into the frazneAandagainst the springs G G, and there be retained by a thumb-pin F, passingthrough the frame A. The operation of our said invention is as follows:When the window is to be cleansed or repaired on its outer surface andwe wish to avoid any danger therefrom should the window be any heightfrom the ground, we first pivot the lower sash by means of the latchpinsE and slide-staples L and remove the stop-bead J by swinging the sameinwardly, when the lower sash will swing in wardly, allowing such repairor cleansing from the inside of the house or room, as desired, withoutany attendant danger. When the upper sash is to be cleansed or repairedon its outer surface, we bring it down to nearly the bottom of theframe, so as to adjust the pin-latches and slide-staples together, so asto form a pivot to said sash, press back the parting-strip against thesprings G G, so that it be retained by the thumb pin in such position,when the sash can be swung inwardly to be cleansed or repaired on eitherside at pleasure. This arrangement admits of the easy adjustment of thewindow-sash as required for cleansing or repairing of either its strip 0springs G G and thumb-pin F subouo er or inner surface. stantialiy asand for the purpose set forth.
